Answer:
7 hours.
Step-by-step explanation:
The outward trip took 5 hours.
We now calculate the distance of this trip:
Speed = distance / time, so
Distance = speed * time.
= 14 * 5 = 70 miles.
So the time for the return journey = distance / speed
= 70 / 35
= 2 hours.
So the time for the entire trip
= 5 + 2 = 2 hours.
